Sorry you are struggling, here's my experience, dumb but want to share: I love cocktails, but like you I hated how I felt afterwards even if I had only 1 or 2.

Sorry you are struggling, here's my experience, dumb but want to share: I love cocktails, but like you I hated how I felt afterwards even if I had only 1 or 2. The energy drain, if it's too late at night have trouble falling asleep, etc. I started asking for mocktails, sometimes they are listed on the menu but many times you can ask the waiter/bartender and they can make you some amazing non-alcoholic drinks even if not listed. I realized I didn't like cocktails, I liked the sugary drink part of cocktails. I still limit to 1-2 mocktails when I go out, and fucking love it. I said cocktails and I know you said beer, but if you also like cocktails maybe that's a way to cut down by tricking your brain into thinking it's having alcohol.
